Abstract

1284538 Turbomachine blades ROLLS ROYCE Ltd 10 Nov 1969 [19 Nov 1968] 54744/68 Heading FIT A blade, e. g. for a turbine or compressor rotor of a gas turbine engine, consists of a core formed of a number of spanwise extending carbon fibre reinforced resin members 20 which are bonded to thin metal strips 22. Each member 20 has a moulded root portion. The concave surface of the blade is covered with a metal sheet 24 formed with integral leading and trailing edge portions 26, 28. The convex surface may be metal plated or covered with cross braced layers 30 of metal plated carbon fibre reinforced resin material.
